We know that agitators are placed in crowds to direct the shouts the way they 'should' go...
But; lest we forget; there were a LOT of others; too; who appeared to 'crucify him' shouters as well:
Matthew 27:52-53
... and the graves were opened; and many bodies of the saints who had fallen asleep were raised; and coming out of the graves after His resurrection, they went into the holy city and appeared to many.
